This Super-Efficient Lightbulb Uses Tesla Tech for an Incandescent Glow

Despite their inefficiency, old-school incandescent lightbulbs sure did put out a pleasant, natural-looking light. The folks at Finally Light Bulb missed that light, so they brought it back with an efficient, affordable bulb using technology Nikola Tesla once patented. The team visited Gizmodo's NYC office to show us… »7/24/14 11:39am7/24/14 11:39am

Purdue University Breakthrough Could Lead to Low-Cost, Mass-Produced LEDs

The researchers at Purdue University are just full of bright ideas these days, and this weekend was no exception. Thanks to a major breakthrough, they may have overcome a major obstacle for "solid state lighting," which laymen like to call LED (light emitting diode). That obstacle? Cost. LEDs are expensive, mostly… »7/20/08 4:00pm7/20/08 4:00pm

'CFL FTW' Illuminates the Tragedy Behind Lightbulb Progress

Poor incandescent bulbs. They had about 100+ years of dominance, but now it's the era of energy-efficient compact fluorescent. And this triumph of the CFL has been archived for future historians in the most permanent record known to our culture: a T-shirt. If you'd like to see this clever garment actually be produced,… »6/16/08 5:00pm6/16/08 5:00pm
